Definitions
- the invention relates to processes for producing alkoxy-rich aminosiloxanes by equilibrating alkoxy-rich partial hydrolyzates with monomeric aminoalkoxysilanes.
- Aminosiloxanes rich in alkoxy groups have hitherto been converted from the monomeric methylalkoxysilanes and the monomeric aminoalkoxysilanes by base or acid-catalyzed cohydrolysis generates. Due to the presence of the basic amino functionalities during the hydrolysis, there is in principle a risk of solid formation or even gelation due to the acceleration of the condensation reactions of silanol groups at increased pH values. In addition, solvent additives are necessary to make the exothermic hydrolysis reaction controllable - these additives, however, significantly reduce the space-time yield of the product synthesis.
- US 9962327 B2 describes a liquid formulation containing the product from the cohydrolysis of 3-aminopropyltriethoxysilane and methyltriethoxysilane.
- EP1580215 A1 describes the preparation of amino-functional organopolysiloxanes by reacting aminosilanes with linear siloxanes and basic catalysts.
- the invention relates to a process for the preparation of aminosiloxanes, in which an alkoxy-rich partial hydrolyzate of silanes, which are independently selected from the general formulas I, Ia, Ib and II [R 1 3 Si (OR 2 )] (la),
- R 1 is a monovalent, unsubstituted or halogen-substituted C 1 -C 20 -hydrocarbon radical
- R 2 and R 4 can be the same or different and are a hydrogen atom or an unsubstituted or halogen-substituted C 1 -C 20 -hydrocarbon radical,
- R 3a is a monovalent C 1 -C 20 hydrocarbon radical containing one or more basic nitrogen atoms or a monovalent C 1 -C 20 hydrocarbon radical which is unsubstituted or substituted by halogen atoms.
- the invention also relates to a process for preparing aminosiloxanes, in which the alkoxy-rich partial hydrolyzate of silanes, which are independently selected from the general formulas I and II [Si (OR 2 ) 4] (I) and
- R 1 is a monovalent, unsubstituted or halogen-substituted C 1 -C 20 hydrocarbon radical
- R 2 and R 4 may be the same or different and a hydrogen atom or unsubstituted or halogen-substituted C 1 -C 20 hydrocarbon radical
- R 3 is a monovalent C 1 -C 20 hydrocarbon radical containing one or more basic nitrogen atoms.
- Partial hydrolyzates in the context of this invention are products from the reaction of silanes or silane mixtures of the general formulas I, Ia, Ib, II, III to V and Illa to Va with water, in which a substoichiometric amount of water is reacted relative to the amount of substance required for the complete hydrolysis of all alkoxy functionalities and as such still contain alkoxy functionalities.
- 0.5 mol of water is required for the hydrolysis of one mol of alkoxy groups OR 2 or OR 4 .
- the incorporation of the amino functionalities takes place via a base-catalyzed equilibration between the partial hydrolyzates and a monomeric aminoalkoxysilane.
- the average degree of condensation of the mixture of partial hydrolyzate and aminoalkoxysilane remains unchanged after equilibration.
- the basic catalyst is used to link OH functionalities (HO-PDMS-OH and HO-glycol or HO-ethylhexane), water being released in the process.
- OH functionalities HO-PDMS-OH and HO-glycol or HO-ethylhexane
- final functionalities are linked there.
- bonds in the partial hydrolyzate and the aminoalkoxysilane are broken and rebuilt by the equilibration without changing the average degree of condensation.
- the incorporation of the aminosilane takes place preferentially. This can be seen in particular from the formation of the methyltrialkoxysilane and the progressive incorporation of the aminosilane (expressed by the state of equilibration) in the examples. This is surprising given the higher steric demand of the trialkoxysilane and the branching in the resin.
